  Many large projects use their own data structures instead of the ones in the
  standard library.  If these data structures are similar in functionality
  to the standard library, they can be instrumented with the same hooks
  that are used to instrument the standard library.
  The instrumentation API is exposed in file
  <code class="code">profiler.h</code> (look for "Instrumentation hooks").
